Electronics

Drawing schematics: (part one)

My favourite drawing tool to create professional looking electronic schemes is gEDA (GPL + EDA = gEDA). It has a simple but efficient GUI and allows tons of shortcuts and as well mouse stroke support. (similar to stroking handhelds with a pen). It already has got a huge library and is easy expandable. Its output is pure postscript or a netlist to create a board later on with another tool.

Drawing schematics: (part two)

xcircuit Another drawing tool to create nice schematics is xcircuit.
- The output generates wonderful postscript code - printable with any good postscript viewer.
- New: It is possible now to import postscript files generated with other programs.
- Libraries: I recently created a chemical library

Metal Detector:

A very nice guy from Trevor sent me a schematic of a metal detector. I haven't built it until now but it looks very promising!
